It's mentioned in the Sony patent 
(https://patents.google.com/patent/US6519676B1/en), although it doesn't 
specify which encoding exactly.

That's interesting thanks. cdrdao doesn't really care actually, the toc 
format just escapes out whatever binary data it finds, but I realized 
cdrdao always burn out the character code as 0 no matter what, which 
isn't ideal. So I'm trying to understand how common those non-0 CDs are...
